| Abstract: | As the second phase grains can raise the fracture toughness of ceramics,they may playan important role in the upgrade of ceramic pressure vessels. Theoretical calculations show.that phase change can increase the nominal stress and the critical internal pressure of vesselsto a great extent. |

| Keywords: | phase change pressure vessel nominal stress stress intensity factor |
